How about something like this?
For (var i:Number=0; I <
dg.dataProvider.length; i++)
{
var cells:Array = [];
var item:Object =
dg.dataProvider.getItemAt(i);
for (var c:Number=0; c <
dg.columns.length; c++)
{
var
col:mx.controls.gridclasses.DataGridColumn = dg.getColumnAt( c );
if (c.labelFunction != undefined)
{
cells.push(c.labelFunction(item));
}
else
{
Cells.push(item[c.columnName]);
}
}
//do something with cells to build your
HTML
}

Let me reformulate my question. Usually you can use selectedItem.
columnName to read the value of a
row/column of a datagrid. This seems to
work fine as shown in the Flex Sample Explorer (
example below). But how
can you read the value of a computed column that
was added in addition to
the columns returned by the
dataprovider? When I trace the selectedItem
or getItemAt, I only get the dataprovider data and
nothing else.
<mx:DataGrid id="dg"
width="100%" height="100%"
dataProvider="{employeeModel.employee}">
<mx:columns>
<mx:Array>
<mx:DataGridColumn columnName="name"
headerText="Name"/>
<mx:DataGridColumn columnName="phone"
headerText="Phone"/>
<mx:DataGridColumn columnName="email"
headerText="Email"/>
<!--
How can I read this? -->
<mx:DataGridColumn columnName="myComputedColumn"
headerText="All"
labelFunction="cocanateAll"/>
<!-- No part of the dataprovider,
but shows OK -->
</mx:Array>
</mx:columns>
</mx:DataGrid>
<mx:Form>
<mx:FormItem label="Name">
<mx:Label text="{dg.selectedItem.name}"/>
</mx:FormItem>
<mx:FormItem label="Email">
<mx:Label text="{dg.selectedItem.email}"/>
</mx:FormItem>
<mx:FormItem label="Phone">
<mx:Label text="{dg.selectedItem.phone}"/>
</mx:FormItem>
<!--
How can I read this? -->
<mx:FormItem label="">
<mx:Label text="{dg.selectedItem.myComputedColumn}"/> <!--
This doesn't work -->
</mx:FormItem>
<!--
-->
Thanks,
</mx:Form>

Subject: [flexcoders] Reading the displayed value in a DataGrid - How
to

Please respond
to
flexcoders
I am using labelFunction for a column in a
datagrid. How can I read the
displayed value and not the real value directly
from the dataGrid?
I am also wondering how to get values from the
DataGrid in general. I need
to render the DataGrid to a HTML table, I mean,
read columns and rows from
the dataGrid and have a string with the HTML
syntax. I could not find
anything such as getRow, and then read each
column. So I am selecting each
Row and then using the selectedItem property.
I know that I could use the function executed in
labelFunction to
reproduce the displayed value, but I am actually
trying to extend the
DataGrid class and add a method called
getHTMLString for example. This
would require to be agnostic of whether the column
has a labelFunction or
not.
Any ideas?
Thanks.
